(已解决)M61-32SU开发板 timer无法触发中断

问题已解决：根据泽哥的方案，换SDK，或者在aithinker_Ai-M6X_SDK/bsp/board/bl616dk/board.c，256行的#endif下加个中断复位函数，bflb_irq_restore(flag);

编译下载sdk下面的timer_int程序，跑起来发现无法触发定时器中断，尝试分析问题无果

换SDK，或者在aithinker_Ai-M6X_SDK/bsp/board/bl616dk/board.c，256行的#endif下加个中断复位函数，bflb_irq_restore(flag);

抓泽哥来给你瞧瞧！

等泽哥解决
